Surgical clips and methods for tissue approximation
First Claim
1. A surgical clip for approximating a first tissue layer to a second tissue layer, the surgical clip comprising a clip body having a distal extremity with a distal end, a proximal extremity with a proximal end and an outer surface therebetween, the distal end being configured to penetrate through both the first and second tissue layers from a first side to a second side thereof without penetrating the first and second tissue layers with the proximal extremity, wherein a first member selected from the distal extremity or the proximal extremity has an inner surface and is shapable into a closed position in which the first tissue layer is compressed against the second tissue layer between the inner surface and the outer surface with both the distal and proximal extremities disposed on the same side of the first and second tissue layers, the clip body being made of a biocompatible material which remains in the body indefinitely to ensure that the anastomosis remains intact, the clip body further having a middle portion configured to be held by a clip applier for applying the clip, the middle portion being separated from the distal extremity to allow penetration of the first and second tissue layers while the clip body is held by the clip applier.

Abstract
Surgical clips, and methods of use thereof, are provided for tissue approximation and attachment, and more particularly, for sealingly joining a graft vessel to a target vessel. The graft vessel has a free end and a graft vessel wall defining a graft lumen. The target vessel has a target vessel wall defining a target lumen and has an opening in the target vessel wall. The anastomosis clip includes a clip body having a distal extremity with a distal end and a proximal extremity with a proximal end. The distal end is configured to penetrate through the graft vessel wall near the free end and through the target vessel wall near the opening such that both the distal and proximal ends of the clip body are outside the graft and target vessels. At least a portion of the clip body is shapable so as to compress the graft vessel wall against the target vessel wall with the target vessel lumen in communication with the graft vessel lumen.
